CHARLES TRUESDALE, OF CINCINNATI, OHIO, ASSIGNOR OF ONE-HALF HIS RIGHT TO WILLIAM RESOR 8c OO., OF SAME PLACE.

IM PROVEM ENT IN COOK-STOVES.

Specification forming part of Letters Patent No. 205,925, dated J uly 9, 1873; application filed May 6, 1878.

To all' whom it may concern:

Be it known that I, CHARLES TRUEsDALE,

' of Cincinnati, Hamilton county, Ohio, have invented certain new and useful Improvements in Cook-Stoves, of which the following is a specification This invention relates to that class of cookstoves which have incased reservoirs located between the rear plate of the stove and the collar or neck to which the pipe is applied; and the first part of my improvements consists in constructing said stoves in such a manner as to enable them being readily converted into six-hole stoves, as hereinafter more fully described.

The second part of my invention relates to a peculiarly-constructed cut-off plate, which is applied to the rear chamber ofthe stoveafter the reservoir has been removed therefrom, the object of said plate being to prevent a too direct current in said chamber and to deiiectthe products of combustion upwardly, so as to more thoroughly heat the culinary vessels on the rear extension of the stove.

The third part of my invention comprises a novel construction of those hearth-plates which are capable of swinging laterally or in a horizontal plane, the details of said platev being hereinafter more fully described.

In the annexed drawings, Figure 1 is aperspective view of a cook-stove embodying my improvements, the reservoir being shown in position and the swinging hearth-plate shut. Fig. 2 is an enlarged vertical section of the stove at the line m, the dampers being shown set so as to cause the products of combustion to circulate under the incased reservoir. Fig. 3 is a horizontal section of the stove at the line yy, about one-half of the reservoir being broken away. Fig. 4 is a vertical section, showing the swinging hearth-plate in its closed condition. Fig. 5 is a plan of the hearth proper of the stove. Fig. 6 is a perspective view of the stove after the reservoir has been removed therefrom and the plate with the two additional holes substituted in the place of said reservoir, the swinging hearth being shown in its open position. Fig. 'Z is a vertical section of the stove at the line z z, the plate with the two additional stove-holes being omitted. Fig. 8 is a similar section in the same plane, but showing the cut-olil or deiiectingplate applied to the rear chamber of the stove. Fig. 9 is a vertical section of the stove at the line .r the two-hole plate and the detlector beingin position; and Fig. 10 is a perspective view of the cut-off plate or deflector removed from the stove. Fig. 1l is a plan of theunder side of the swinging hearth-plate, the central portion of said plate being broken away.

A represents the top plate, B B the side plates, and C the rear end plate, of a cookstove of any approved size and shape, said top plate bein g provided with four customary holes, l 2 3 4, and a collar, a. D represents the oven, and E F F represent respectively the central and the two side lues at the rear end of said oven. G is the upper, and H the lower, damper of the central flue E, said dampers being provided with customary handles g h.v

I is a chamber, located between the rear plate C and flues E F F', nue-strips J J being arranged so as to compel the products of combustion to take a circuitous route through said chamber, as indicated by arrows in Figs. 2 and 3. Incased or inclosed within this chamber I is a customary reservoir, K, whose bottom rests upon the upper edges of iiue-strips J J', and also upon the horizontal and rearwardly-projecting iiange c of central ilue E. Furthermore, the exposed portion of this reservoir has a marginal ange, k, and one or more hinged lids, L L.

All of the above-described parts are admitted to be old in what is commonly known as incased reservoir-stoves 5 but, in order to render such appliances readily convertible in to a six-hole cook-stove, I cast on the upper surface of plate A a rectangular or other suitable shaped bead or rib, M, which not only receives the flange k of the reservoir, but said bead also retains a removable plate, N, having two holes, 5 and 6, as seen in Fig. 6.

I also provide chamber I with two grooves or other guides, O O', for the reception of the vertical flanges p p' of the cutoff or deliectin g plate P, which plate has at bottom a rectangular opening, It, that spans the liuc-strips J J', as seen in Fig. S, the horizontal flange r of said plate resting upon flange e of central flue E, as represented in Fig. 9. This plate has two curtains, Q Q', that close the passages between tine-strips J J and the side plat-es of chamber l, the upper portion of said plate being dished or coneaved at q to avoid contact with the cooking utensils applied to the holes 5 or 6.

The hearth of my stove consists of two similar-shaped wings, S S', united by a web, s; but said members are Ilot all situated in the same horizontal plane, the ones S and s being somewhat lower than the one S', in order that the swinging hearth plate or shelf T may be perfectly level either when swung aside so as to aiord access to the pit Z or when shut over said pit. The left rear corner of this plate or shelf has a downwardly-projccting pivot, U, with a lateral lug, il, said pivot and lug being adapted to pass through the eye or perforation V c of the wing S of the hearth when said plate is applied to the stove.

t is a pull or handle of any kind, wherewith said plate is manipulated. The free or right edge of said plate has on its under side a rib or tiange, W, whose advancing end is chamlered olf at 1c to slide readily against the wedgeshaped lug X of a flange, Y, which latter projects inwardly froin the right wall of ash-pit Z.

The wedge X serves to draw the free edge of hearth-plate T up snugly against the wing S' of the hearth proper, as seen in Fig. 4. Hearth-plate T is grooved or channeled, t', 011 its upper surface, which crease t' is about as far distant from the left edge of said plate as is the free edge ot' said plate from the right side of the stove, as lnorc clearly shown in Fig. 1.

When reservoir K is used, thc operation of the stove is the same as ordinary four-hole stoves, which operation, being clearly indicated by the arrows in Figs. 2 and 3, requires no further description.

The stove can be readily converted into a six-hole stove by first lifting out the reservoir l and then applying the cut-oft` plate I to chamber I, care heilig taken to insert the anges p p' of said plate in thc guides or grooves 0 0' of the sides B B'. Ilate N is then applied to top plate A, so as to tit snugly within the bead M, as seen in Figs. 6 and 9.

.As the curtains Q Q' of plate l cut off all communication between the lower portions of side lines F F' and chamber I, it is evident the products of combustion can escape only by passing transversely across the concave q of said plate, after which the tire and smoke descend in the rear of chamber l, and finally escape between the iiue-stripsJ J', and thence up the central channel E, as clearly indicated by the arrows in Fig. 9. By thus deliecting the products of combustion upwardly by means of plate P q any vessels that may be seated in the holes 5 and 6 are heated in the most thorough manner.

By simply lifting oif the plate N, withdrawing delector P, and replacing water-tank K, the stove is at once converted into an incascd reservoir stove, and without changing the dampers.

By causing my hearth-plate to extend in a horizontal plane continuously from the wing S' to the pivot U a perfectly level and unobstructed surface is afforded for the reception of all kinds ot' culinary vessels, &c.; and it is evident such vessels will remain securely in position,no matter whether said plate T is open or shut.

It is also apparent that, by dropping the wing S below the level of wing S', or vice versa, the plate T is capable of being swung in either direction, and without lifting it bodily either in opening or closing said plate.

I am aware it is not new to pivot a hearthplate to the hearth proper, and therefore my claim to this device is expressly limited to the plate T when combined with a stove having one of the wings S or S' dropped below the level of the opposite wing, in order that said plate may open and close in a horizontal plane from its junction with said wing to, or nearly to, the opposite edge of the hearth proper, the upper surfaces of these members T and S or S' being flush with each other when the former is in its closed condition, as seen in Fig. 1.

Finally, the deiiector I may be made in two or more sections; but I prefer to cast it entire, so as to chcapen its construction and facilitate its application to the stove.

I claim as my invention- 1. An incascd reservoir-stove capabloof being readily converted into a six-hole stove by fitting in the rear portion of the same a detachable plate, which plate cuts off the downward or direct exit of the products of combustion and detlects them upwardly, substantially as herein described.

2. In combination with the iues E F F' and chamber I of an incascd reservoir-stove, the deflector l p p' Q Q' R and grooves O 0', substantially' as herein described.
